We look at the division of 256205 by 15 
Let's see how many times 15 fits into 256205.

Step 1:
2 divided by 15 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 15

Going ahead to step 2:
15 goes into 25 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 10 after subtracting 15 from 25.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 15

Let's proceed to step 3:
The number 15 fits into 106 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 1 after subtracting 105 from 106.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 15

Moving on to step 4:
If we divide 12 by 15, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 15

Advancing to step 5:
120 divided by 15 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1708.0
Deduct 120 from 120 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 15

Advancing to step 6:
15 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 17080.0
If we subtract 0 from 5, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 17080.3
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 17080.33
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 17080.33, and the remainder is 0.005.
